Special Heatran training in Atk and SpDef? I hope this is a typo.

Gengar : Use Focus Blast >>> Energy Ball. Despite imperfect accuracy, it OHKOs Tyranitar and Bisharp while also dealing super effective damage against Heatran.

Amoonguss shouldn't be used as an offensive Pokemon. It should only be invested in defenses. Also, is your Amoonguss' ability Regenerator? I actually wanted to replace Amoonguss with Mega Venusaur if it does not have Regenerator, but then Aerodactyl would not have a mega, and thus unable to deal with Mega Salamence.

Your team in general lacks a wallbreaker or setup sweeper. No particular Pokemon can break through walls or sweep. I think Excadrill > Lucario can be a good replacement. Gigalith sets up Sand Stream, Excadrill can take advantage of that with Sand Rush. And with Excadrill's power, especially when boosted with Life Orb or Swords Dance, it can break through walls easily. It can also be used as an emergency speed check to certain Pokemon.
